MMP-2 Inhibitor II is an irreversible, potent and selective MMP-2 inhibitor with Ki value of 2.4 μM [1].
Matrix metalloproteinases (MMPs) are zinc-dependent endopeptidases that play important roles in physiological and pathological conditions. Two MMPs, gelatinases A and B (MMP-2 and MMP-9, respectively), is highly expressed in human cancer, and a direct relationship between cancer progression and gelatinase expression and activity has been well established [1].
MMP-2 Inhibitor II, an oxirane p-sulfonamido analog of SB-3CT, is an irreversible, potent and selective MMP-2 inhibitor. MMP-2 Inhibitor II inhibited MMP-2, MMP-1 and -7 with Ki values of 2.4 μM, 45 and 379 μM, respectively, and didn’t inhibit MMP-3, -7, or -9 [1]. In bovine retinal endothelial cells, MMP-2 Inhibitor II reduced glucose-induced increases in the gelatinolytic activity of MMP-2 and mRNA levels of MMP-2 and MT1-MMP. MMP-2 Inhibitor II also inhibited glucose-induced alterations in TIMP-2 and MT1-MMP gene expressions [2]. MMP-2 Inhibitor II had also been used to examine the role of MMP-2 in rheumatoid synovial fibroblast survival, inflammation, and cartilage degradation [3].
